Answer:

[tex]V=0.135\ units^3[/tex]

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to teh scale factor elevated o the cube

Let

z ----> the scale factor

x ----> the volume of the dilated prism

y ----> the volume of the original prism

[tex]z^3=\frac{x}{y}[/tex]

we have

[tex]z=\frac{1}{10}[/tex]

[tex]y=135\ units^3[/tex]

substitute

[tex](\frac{1}{10})^3=\frac{x}{135}[/tex]

solve for x

[tex](\frac{1}{1,000})=\frac{x}{135}[/tex]

[tex]x=135/1,000=0.135\ units^3[/tex]
